A lot of people report DHTs wrecking their hair. People even report test dosages taking a toll on their hair and it gets worse the higher you go.
You can mitigate hair loss from test with finasteride oral or topical as well as dutasteride. You cannot do anything about DHTs except apply a topical anti-androgen to your scalp like RU-58841.
You have to come up with a plan or make some trade offs. Take finasteride/dutasteride, apply RU-58841, apply minoxidil, and use ketoconazole shampoo a few times a week. That’s what I do at least, and I run primo with no recession now.
Some people also microneedle their scalp but I don’t have experience with that. I’m vain, but I don’t have time for all that.
Also you can pony up and get a hair transplant to start over fresh. Then implement the above procedures to maintain. That I do have time for, and I will be doing.
